Addendum: Just as a reference point, attached is a PNG of the same
comparison except with the math-mode "S" wrapped by \mathrm, as in:


Both CM and TR put space between the roman letter and the subscript, but
 there's no marked difference (TR puts a tiny bit more space, but it's
hardly noticable). The problem with TR in the original example
definitely seems to involve the math-italic status of the subscripted

For posterity, here are the relevant logs for this second comparison,
first, for CM:

  .\OT1/cmr/m/n/10 S
  .\hbox(4.63193+0.0)x3.32928, shifted 1.49998
  ..\OML/cmm/m/it/7 i

and for TR:

  .\OT1/txr/m/n/10 S
  .\hbox(4.5745+0.05249)x2.446, shifted 1.49998
  ..\OML/txmi/m/it/7 i
